Name: FHWA Model Systems Engineering Documents for Central Traffic Signal Systems
Description: This document is intended to provide guidance for professionals involved in developing systems engineering documents covering the evaluation, selection and implementation of Central Traffic Signal Systems. (CTSS). It includes initial user needs, system requirements, and template statements that can support efficient development of a Concept of Operations, a Requirements Document, a Verification Plan, and a Validation Plan. The CCTS may be a brand new deployment or an expansion of an existing system.

The Model Systems Engineering Documents for CTSS are intended for projects with the following characteristics:
* Relatively small, such that the project budget cannot be reasonably expected to fund systems engineering document development from scratch.
* Constrained to existing products in the market. The model documents are not intended to provide the detail necessary to support new significant software development.
* Applications of CTSS already well-defined in the transportation industry.

Agencies building large projects with custom software development or innovative applications will need to perform more detailed custom systems engineering, though these documents may provide an effective and time-saving starting point for that effort.

Name: Ohio System Requirements Workbook
Description: The Ohio CV/AV System Requirements Workbook outlines functional requirements for all CV/AV deployments in Ohio. Ohio project owners should follow these as a baseline to meet project-specific requirements and procurement documentation, which support overall function of any CV application and set the stage for interoperability among various deployments. The provided link includes a number of requirements document downloads organized by application and focus area. I link to guidance on how to use the Workbook is also available.

Name: PennDOT TSMO Design and Integration Guidelines
Description: The intent of this guide is to serve as a reference to design consultants, contractors, and network integrators on key items that should be considered during the various phases of a PennDOT Intelligent Transportation Systems (ITS) design project for successful integration of ITS devices into PennDOT's Advanced Traffic Management System (ATMS) software platform and/or PennDOT's Video Management System (VMS). The main body of the document provides the design guidance. Two appendices provide sample systems engineering documentation for a typical simple project that adds a few devices and a complex project that implements new variable speed limit and queue warning capabilities to a corridor. Each appendix includes a sample ConOps, System Requirements, a system design with specified device locations, a communications plan that includes an integration plan, maintenance and operations overview, a cost assessment, and a procurement strategy.

Name: Rural Connected Vehicle Corridors - Model System Requirements Specification
Description: NCHRP Research Report 978 provides state and local transportation agencies with a systems engineering approach for planning the integration of connected vehicle technologies along roadways in rural corridors. This document is a model System Requirements Specification (SyRS), meaning it contains information that will apply in general to most current and proposed systems, and it is intended to be a starting point for deployers. It addresses the core, common priorities and provides a base document that a deploying agency can customize to their project and situation. It is not written for a specific implementation and does not address a transportation agency's unique operation and system management.
